project into a public way not over seven inches. 
Water pipes in every building shall be properly 
protected from frost. Every building where 
persons are employed shall have at least one 
water-closet for every twenty persons therein One water-

water-closet, such compartment shall not be 
less than two feet four inches wide, and shall be 



enclosed with plastered partitions, or some

over it, no window shall be necessary, provided 
the roof of such skylight contains at least three 
square feet of glazed surface and is arranged 
so as to readily open. Nothing in this section in 
regard to the separation of water-closet compart- 
ments from each other shall apply to a general 
toilet room containing several water-closets, 
hereafter placed in a tenement house, provided 
such water-closets are supplemental to the 
water-closet accommodations required by law 
for the use of the tenants of the said house. 
Nothing in this section in regard to the ventila-
